BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a fence; especially relates to an adjustable fence.

2. Description of the Prior Art(s)

Fences are freestanding structures designed to restrict or prevent any transgression of strangers or animals across a boundary. Fences are generally distinguished from a wall by the lightness of its construction made by wood instead of solid bricks or concrete.

A conventional fence has multiple wooden slats. The wooden slats are arranged in a column or row and assembled together by fasteners such as nails. However, the fence with the fasteners tightly holding the wooden slats does not allow quick attachment or removal of wooden slats for height adjusting purposes. Attaching wooden slats to or removing wooden slats from the fences needs hand tool to mount or detach fasteners thereon, which wastes too much time and lowers the efficiency of adjusting the height of the fence.

To overcome the shortcomings, the present invention provides an adjustable fence to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The objective of the present invention is to provide an adjustable fence.

The adjustable fence comprises two posts separated from each other at an interval, a slat assembly slidably and detachably mounted between the posts, and two buffering elements. Each of the posts has a post body having a top end and a bottom end, and a mounting slot formed transversely in and extending longitudinally along the post body. The slat assembly has multiple detachable slats slidably and detachably mounted in the mounting slots of the posts. The buffering elements are respectively disposed in the mounting slots of the posts. Each of the buffering elements is disposed between the post body of each of the posts and the slat assembly.

Increasing or decreasing the detachable slats of the slat assembly adjusts the height of the adjustable fence for different applications. The pushing force resulting from the thermal expansion or/and contraction of the slat assembly or/and the post body is absorbed by the buffering element, so that the bottom bracket of the slat assembly and the post body do not push each other to be deformed.

Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The detachable slats 21, the bottom bracket 22, and the top bracket 23 of another adjustable fence 1 are mounted in one of the expanding slots 13. As such, combining multiple adjustable fences 1 of the present invention together for a fence assembly or an enclosure as desired is achieved.

Based on the above, the adjustable fence 1 has the following advantages.

The height of the adjustable fence 1 can be quickly changed by increasing or decreasing the detachable slats 21 of the slat assembly 20 for different applications. Therefore, adjusting the height of the adjustable fence 1 is easy and efficient.

The bottom bracket 22 guides the lowest detachable slat 21 to easily fit the bottom bracket 22 and prevents the detachable slats 21 from bending at an intermediate section due to a heavy total weight of the slat assembly 20. Therefore, the bottom bracket 22 plays an important role that guides and supports the slat assembly 20 to prevent any inadvertent deformation.

The top bracket 23 holds the detachable slats 21 to prevent the detachable slats 21 from being detached inadvertently.

The limits 30 with the first fastener 34 and the second fastener 35 securely hold and press against the slat assembly 20 to prevent the detachable slats 21 from being detached inadvertently and enhance an overall structural strength of the adjustable fence 1.

The pushing force resulting from the thermal expansion or/and contraction of the bottom bracket 23 or/and the post body 11 is absorbed by the buffering element 40, so that the bottom bracket 23 and the post body 11 do not push each other to be deformed.
